Encina MACHINE.

Application led .Tuly 11,

To all whom t may concern:

Be it known that I, PAUL H. LANGE, a citizen of the United States, and a resident of Bridgeport, in 'the -county of Fairfield and State of Connecticut, have invented'certain new and useful Improvements in Edging Machines, of which the following is a specification.

This invention relates generally to edging machines and has for its main object and feature av machine for edging segmental shaped blanks of varying sizes and different degrees of angularity of sides so arranged that the machine may be adjusted to act on di'erent segmental shaped blanks passing through the machine in a given path.

In the accompanying drawings the invention is disclosed in a concrete and preferred form in which Figure 1 is a front elevation of a machine embodying the invention:

Fig. 2 is a plan view thereof:

Fig. 3 is a fragmentary plan view of the tool heads and adjacent elements with parts broken away and in section: v

Fig. 4 is a vertical longitudinal section on the plane of line 4-4 of Fig. 2:

Fig. 5 is a view, similar to Fig. 4, of the two tool heads showing the jaws in their retracted position: Y Y

Fig. 6 is a detail sectional view on the plane of line6-6 ofV Fig. 2 showing one of the holding pawls of the feed mechanism:

Fig. 7 is a detail sectional view on the line 7-7 of Fig. 3:

Fig. 8 is a longitudinal vertical sectional view through the feeding mechanism on the plane of line 8 8 of Fig. 1.

1 is a suitable blank feeding mechanism here shown as a reciprocating carriage sliding in'suitable ways 2 for feeding a blank intermittently through the machine: `The particular blank here in question is indicated in dotted lines 3 of Fig. 2 and is,'in the present instance, a segmental shaped section of a tub, a number, greater than two, of which are united to form the tub. In order to properly unite them, Vit is desirable to provide the side edges of the blanks with hooks, as 4 (Fig. 5), to form a lock'seam. It will be understood that, depending upon the size of the tub to be made, the size, the shape of the blank and the degree of angularity of the side edges thereof will vary and therefore it is an object of this invention to make 1922. seria No. 574,333.

the machine adjustable so that blanks ofdifferent size and shape can be properly edged.

Arranged on either side of the reciprocating carriage 1, which feeds the blank in a given path through the machine, is a guide 6 on which is aV slide 7. The two slides 7 are Aarranged to be moved toward and away from each other by any suitable means, here tak,- ing the form of a rotatable rod Siactuated by a handle 9 and devoid of lengthwise movement. This rod is provided withV right and f stood that, whatever the adjusted position of Y the slides, power will be transmitted to the upright shafts. Power may, of course, be transmitted to themain shaft in any suitable way, as by means of pulley 16, on power shaft 17, pinion 18 and spurgear 19.

Each of the-slides '7 is provided with a circular way 20,v concentric` vwith the a-Xis of rotation of Vvertical shafts 10, and mounted on each of said slides isa head 22 P n n u A clrcumferentially adjustable on' circular Y* ways 20 and Aprovided with arcuate slots 23 and bolts 24 whereby the heads may be secured in any position to which they have beenadjusted. Each of 'the heads also carries an edgingy tool here shown as being i composed of two jaws 25 and 26 which coact to form a hook on each side edge ofthe blank.

It will be observed that by these means the aws aforesaid may be made parallel to the side edge of the blank notwithstanding that said side edge is not paralleltothe given path of the blank'through the machine. Jaws 25 and 26 are'pivotal'ly supported at 27 and 28 and are actuated by means of levers 29 and 30, rollers 31 and 32 and cams 33 and 34 mounted on cam shaft 35. Shaft 35 receives motion from the upright shaft by means of bevel gear 36. From the foregoing, it will be understood that power will be transmitted to the cam shaft, and therefore to' the' jaws, regardless of the position circumferentially occupied by the head. t will also be clear that the jaws areso arranged (Fig. 5) that the large rear end oft the blank will not interfere with the jaws when the latter are in their retracted position and said blank is passing through the machine. Bolts Q-i are et noteworthy construction. As shown in Fig. 7, each bolt 24 carries, at its lewe-rend, al head 36 which is seated in a straight slot 37 of the guide.

rlhe means for feeding the sheets through the Vmachine rmay take many forms. As shown, the'sheet is y placed upon the reciprocating carriage l and Vnpon ledges 3,8. ciprocating carriage 1 is given an intermittent movement by means ot crank 39, on the main shaft, connection 40, vbell crank -l-l and link 42. Bell 'crank 4l is mounted on -rock 'shaft 42a and one-of Vthe arms of the bel'lcrank is provided with a :series ot bolt holes 43 so that the amount of feeding movement may be regulated. Mounted on the reciprocating carriage are pusher iin- .gers 44 V'that carry the v sheet to a position beneath rollers 45, which are iotz..table 'in either direction, and, to a point beyond stop lpawls 45, pivot-ally.mounted Ain the stationary framework. 'Upon the return 'stroke of fthe reciprocating caifragc, fthe "friction, caused 'by interposition of the vtin sheet, between fthe carriage and the rollers vmoves the sheet `rearnardly to a slight extent against 4the stop pawls zthat act as `gages `to position the sheet with respect to the edgingdevice. `l/Vliile 'in this posit'cn .the vedging operation takes place. Upon the next 'forward `stroke ot' the reciprocating carriage, pawls l? engage the rearfend vof the blank and feed it 'forward between stationary guide 48 and vfriction roller 49 where the sheet remains during the return .stroke of the carriage. Upon thev next reoipr'ocation of the carriage, paw'ls 50 push 'the sheetfout of 'themaehine Pawls 417 and 50 are of a type well'lnown in this art, viz: they are biased, by springs lor gravity or both, to normally project above the plane of 'the blank and are depressed on Vthe return stroke of the carriage. Pawls i6 are Ydepressed Aon the `forward vstroke oit the carriage.
